Hi ,
This seems to leave us with the Hard Disc .
Regards .

Defective LED back lights strips, or damaged EEPROM on main board. I will try a main board first, if you do nor have a TV LED strip tester.

Call for warrenty serviced,u still have warrenty inforced until a year.Ur tv have intermittently signal shutdown before it come throught the Tuner board not,carrying to the LCD Screen to produced a picture.

I have a 3 year old TV with the same problem as shema_ross.

you need a master reset

It sounds like two possible things. One thing may be that your screen is not working anymore. Can you get a monitor and plug it into your port located on the side of your laptop? If your screen pops up on the monitor this tells us your screen is either in need of replacement or a connection may be loose.

If that is not the case......

Another thing is your hard drive may not be initiating. If you feel confident enough I would open the back where the hard drive is located and make sure the hard drive is not loose. Does it give you any beeping sounds when you turn it on? Can you count the number of beeps? This will tell you what the problem is on boot up. Also, is it a black screen with a cursor blinking?

This sounds like the power supply that feeds your back-light is going out. This repair should be done by a qualified technician

Get a RMA by TomTom by callinging them directly (see on TomToms webpage) I've solved by shipping my unit to Neaderland with UPS at no cost, they replaced the motherboard (not the display, this  just remained the same!) I've received the repaired 910 after 5 days and I've spent no one cent! And I've got also the battery, AC power supply and software replacement! Other problems of the software are still present: the unit won't cange colors by night-light changes (only one time after a reset...), tryes to connect to phantom computers, after a power on it get off and then on if connected on the car support,... The 910 is a crazy device, not stable at all. I think I'll change it with the new model Go930T Ciao (sorry for my bat english)
